What is potassium Humate

Potassium humate is a non-uniform aromatic hydroxycarboxylate with a black granule or powdery solid. It is soluble in water and alkaline. It contains active groups such as carboxyl groups and phenolic hydroxyl groups.

The product is non-toxic, tasteless, black natural organic powder. Soluble in water, it is a kind of functional potassium humate with a large number of intricate, strong adsorption, strong chelation ability, the best fertilizer to promote potassium, repairing soil strong organic macromolecular compounds, more resistant to microbial decomposition, its decomposition is slow It is the crown of all organic solid fertilizers.

It has strong adsorption, exchange, complexation and chelation ability. It is the best indicator for maintaining fertility. It is also known as ecological fertilizer and can be used for slow-acting nitrogen, phosphorus and potassium. organic fertilizer.

Potassium humate is a high-efficiency organic potash because humic acid is a biologically active preparation that increases soil available potassium content, reduces potassium loss and fixation, increases potassium uptake and utilization by crops, and improves soil.

The main functions of potassium humate:

It can promote crop growth, improve crop resilience, improve crop quality, and protect agricultural ecological environment. It can be combined with urea, phosphate fertilizer, potassium fertilizer, trace elements, etc. to produce high-efficiency multi-functional compound fertilizer.

1) The humic acid functional group in potassium humate can absorb and store potassium ions, prevent water loss in sand and leaching soil, and prevent potassium from being fixed in sticky soil.

2) Some parts of potassium humate are low molecular humic acids such as fulvic acid, which have a dissolution effect on minerals such as potassium silicate and potassium feldspar, which can slowly decompose and increase the release of potassium and increase the content of available potassium. It is 87%–95% higher than the utilization rate of common potassium fertilizer, which increases fertilizer efficiency, improves crop yield and improves quality.

3) It has the special effect of combining land and land; long-acting and quick-acting coordination; water-retaining and fertilizer-retaining effects; it combines the advantages of inorganic fertilizer and farmyard manure and is superior to them, with good nutrient release regulation The function is a good controlled release fertilizer, so that the nutrient is not too much in the early stage, the nutrient is not too low in the later stage, and the fertilizer supply curve is stable.

The release rate can also be controlled by physical and chemical biotechnology to achieve two-way regulation of sustained release and sustained release. The balance between the supply of nutrients in the fertilizer and the demand for nutrients in the crop is basically synchronized to achieve a dynamic balance.

4) Ordinary chemical fertilizers can easily cause soil compaction and pollution to water and gas, and potassium humate can be avoided or significantly reduced. And obviously high crop yield, improve crop quality, improve crop nutrient content, nitrate content, color, aroma, taste and storability. It is the material basis for agricultural clean production and green food with environmental protection functions.

The loss of potassium humate is low, the utilization rate is high, the plant absorption is stable, and the yield and quality are improved in both directions. It is a “green” potash fertilizer for agricultural application and a substitute for ordinary agricultural potassium chloride and potassium sulfate. Potassium humate is suitable for any crop and can also be applied in combination with common fertilizers.

The role and efficacy of potassium humate

Potassium humate is a high-efficiency organic potash with high molecular weight dissolved in water.
1) It can improve soil physical characteristics, improve soil aggregate structure, reduce soil compaction, and achieve good conditions.
2) Increase the cation exchange capacity and fertilizer retention capacity of the soil to adsorb and exchange plant nutrients, improve the slowness of fertilizer, and increase the ability of soil to maintain fertilizer and water retention.
3) Provide activities for soil beneficial microorganisms.
4) Promote the decomposition of artificial (such as pesticides) or natural toxic substances and effects.
5) Increase the soil’s ability to balance and neutralize the soil pH.
6) Color black helps absorb heat and plant in early spring.
7) Directly affect the metabolism of cells, improve the respiration and photosynthesis of crops, and enhance the resilience of crops, such as drought resistance, cold resistance, and disease resistance.
8) The nutrients required to release the plants after decomposition.
9) Strong roots increase yield, improve crop quality and increase sweetness.

How to use of potassium humate:

1) It can be used as top dressing and base fertilizer, and can be applied, applied, and applied.
2) It can be sprayed on the ground and on the foliage.
3) Suitable for crops such as fruit trees, tea, citrus, grapes, strawberries, various trees, flower trees, flowers, melons, vegetables, rice, etc.
4) The root is watered with an aqueous solution; the leaf surface is sprayed with an aqueous solution and moistened.

Potassium humate application Dosage

  1. Base fertilizer: 5-10kgs/ ha, suggested mix with N, P fertilizers.Mixed with Nitrogen fertilizer: 5% of total blend ie. 5kgs per 100kgs of Urea. Also it depends on the soil condition.
  2. Soil irrigation:5-8kgs/ha/time
  3. Caution:Before transferring to drip irrigation tank we suggest dissolve in a small tank and filtering
